DISCLOSURE OF INVENTION Problems to be Resolved by the Invention

The container for a medical device shown in Patent Document 1 is constituted by forming an opening at the top portion, mounting a holder in the container for holding a medical device, holding the medical device in the holder, sealing the opening by a cover which is gas permeable and bacteria non-permeable and wrap-packaging the entire sealed container.

The container for a medical device shown in Patent Document 1 is delivered to a pharmaceutical company or a medical institution after sterilization, however, in general, it takes a lot of trouble because it requires operations for removing the wrap package under a sterilization environment and then removing the cover which seals the opening portion of the container in order to utilize the medial device at the delivered site. Especially, when a medical agent is filled in the medical device using a filling machine by an automated process, it was not easy to remove the wrap package in such a process.

Therefore, the task of the present invention is to provide a container for a medical device which can significantly reduce labor hour for removing the seal at a delivered site, e.g., a pharmaceutical company or a medical institution by making the removal of the package easier. Furthermore, the task of the present invention is to provide a container for a medical device which enables an easy removal of the package even during an automated process in a filling machine for filling a medical agent in the medical device.

The inventor of the present invention studied hard to resolve the above-mentioned problem. Consequently, the following invention was made.

(1) A container having an opening portion at its top portion and housing a holder for holding at least one medical device, wherein the opening portion is sealed by a gas non-permeable film.

(2) A container described in (1), wherein the container, the medial device, holder and the gas non-permeable film are sterilized.

(3) A container described in (1) or (2), wherein the gas non-permeable comprises a sterilizable film which can be sterilized by gas, steam or radial ray and a gas non-permeable film, and the sterilizable film is positioned on the side contacting the container.

(4) A container described in either one of (1) through (3), wherein the space between the sterilizable film and the gas non-permeable film is sterilized.

Means for Solving the Problems

In a container for a medical device according the present invention, it is possible to significantly reduce the labor hour for removing a seal at a delivered site like a pharmaceutical company or a medical institution by removing a package easily. Furthermore, it is possible to remove a package easily during an automated process in a filling machine for filling a medical agent in the medical device.

Additionally, in a container for a medical device according the present invention, it becomes unnecessary to sterilize the medical device again at a delivered site of the medical device which is housed in the container.

By this arrangement, it is possible to efficiently fill a medical agent during an automated filling process for filling the medical agent in a medical device like a vial, and additionally it is possible to easily perform an automatic capping of a rubber plug to a medical device like a vial after the medical agent filling. Furthermore, during a sterilization of the outer side of the container by a sterilization gas, the medical device and its holder in the container are not exposed to gas because the sterilization gas does not go into the container with the aid of the gas non-permeable film.

It is also possible to deliver the container to a user in a condition where the outer side of the container is sterilized when the entire container is covered by a gas non-permeable film.

MODE FOR IMPLEMENTING THE INVENTION

[Embodiment 1]

FIGS. 1 through 7 show the embodiment 1 of a medical device container 1 according to the present invention. As shown in FIGS. 1 through 3(C) and 7, the medical device container 1 according to the embodiment 1 comprises a container body 2 having an opening at the top portion, a medical device holder 4 which is housed in the container body 2 and a gas non-permeable film 3 for sealing the opening portion at the top portion of the container body 2.

As shown in FIGS. 1 and 2(A) and 2(B), the container body 2 is formed in a basket (box) shape having a nearly rectangular planer shape, and comprises a circular flange portion 22 which is formed at the opening portion of the top portion to extend circularly and outward and an uneven portion 23 which is formed circularly at a position which is lower than the circular flange portion 22 by a predetermined length toward the bottom. The planer shape of the container body 2 may be a polygonal shape, a circular shape or an oval shape, other than the nearly rectangular shape shown in the drawing. The container body 2 is formed by synthetic resin, metal or various composites of these materials.

The gas non-permeable film 3 seals the circular flange portion 22 of the container body 2 such that they are peelable by heat welding and the like, and then seals the opening portion at the top portion of the container body 2. It is preferable that the gas non-permeable film 3 comprises a gas non-permeable film which blocks gas, steam, bacteria, etc., and a sterilizable film which is positioned and stacked on the side contacting the container body 2. It is also possible to seal the opening portion by sealing the circular flange portion 22 of the container body 2 with the sterilizable film by heat welding and the like such that they are peelable, covering the entire container by the gas non-permeable film 3 and then packaging the container body 2 by vacuuming. The sterilizable film passes gaseous matter for sterilization like gas, steam or the like, but does not pass bacteria, and is formed by filaments of high density polyethirene or other polymers, for example.

It is possible to use “Tyvek” (Registered Trademark) made by DuPont as a sterilizable film and a film made of polyvinylidene chloride, high density polyethylene, polyethylene terephthalate or the like as the gas non-permeable film.

The medical device holder 4 is placed alone inside the container body 2 or plural medical device holders 4 are stacked and placed in the container body 2 as shown in FIG. 7 to house the medical device holder 4 in the container body 2. As shown in FIGS. 3(A) and 3(B), the holder 4 comprises a plate-like basal plate portion 41 and plural tubular portions 42 protruding downward from the basal plate portion 41. The shape of the basal plate portion 41 may be nearly rectangular as shown in the drawing, circular, oval or polygonal. The number of tubular portion 42 and the distance between neighboring tubular portions 42 are not limited specifically, however it is preferable to place the neighboring tubular portions 42 at nearly equal intervals. By this arrangement, it is possible not only to place a large number of tubular portions 42 but also to prevent neighboring medical devices from contacting each other even when elongated medical devices are housed in the tubular portions 42. The tubular portion 42 has a top end opening portion 44 which opens on the side of the basal plate portion 41 and a bottom end opening portion 43 which opens downward, and the top end opening portion 44 and the bottom end opening portion 43 are communicated.

As shown in FIGS. 4(A) and 4(B), a circular convex portion 48 is formed at an upper position from the bottom end by a predetermined length on the inner surface of the tubular portion 42. For example, when a piston 61 as a medical device is housed in the tubular portion 42, the piston 61 is kept in a hanged condition by the circular convex portion 48 to prevent the piston 61 from passing the circular convex portion 48. The circular convex portion 48 may be continuously or intermittently circular. The inner surface of the tubular portion 42 may have a tapered shape which has a diameter decreases upward or downward along the tubular portion 42. The circular convex portion 48 may be formed to make the inner diameter of the portion for a predetermined length from the bottom end (the portion which is lower than the circular convex portion 48) smaller than the inner diameter of the holder 4 at the top end opening portion.

FIG. 4(B) shows a condition where the piston 61 is inserted from the top end opening portion of the tubular portion 42, a first rib (formed at a position nearer to the tip) 611 passes the circular convex portion 48, a second rib 612 does not pass the circular convex portion 48 and is held at the circular convex portion 48, and the piston 61 is kept hanging.

As shown in FIGS. 3(A), 3(B), and 3(C), a side support rod 45 is formed in the peripheral portion of the holder 4 by protruding downward from the basal plate portion 41, and a center support rod 46 is formed in the center portion of the holder 4 by protruding downward from the basal plate portion 41, The side support rod 45 and the center support rod 46 are longer than the tubular portion 42 so that a medical device (not shown in the drawings) housed in the tubular portion 42 contacts neither the bottom surface of the container body 2 nor water on the bottom surface, and does not contact neighboring holders 4 when the holders 4 are stacked.

As shown in FIGS. 5(A)(a), 5(A)(b), 5(B)(a), 5(B)(b), 5(C)(a), 5(C)(b), 5(D)(a), and 5(D)(b), the side support rod 45 comprises a base portion 451 which extends from the basal plate portion 41 by a predetermined length and a connecting support rod portion 452 from the base portion 451 to the tip, and the base portion 451 has a connecting hole 47 forming a recess (a recess for housing the tip of the connecting support rod portion 452 of the side supporting rod 45 of a holder 4 which is positioned above, when multiple holders 4 are stacked) which extends from the side of the basal plate portion 41 toward the side of the connecting support rod portion 452. The base portion 451 may have a circular cylinder shape, an elliptic cylinder shape or a rectangular cylinder.

As shown in the examples of FIGS. 5(A)(a), 5(A)(b), 5(B)(a) and 5(B)(b), the connecting support rod portion 452 may be a rectangular cylinder having a crisscross cross-section shape or a rectangular cylinder having a cross-section shape extending radially in three directions. As shown in the example of FIGS. 5(C)(a) and 5(C)(b), the connecting support rod portion 452 may have a circular cylinder shape from the base portion 451 for a predetermined length and may have a nearly circular cone shape from the end of the circular cylindrical portion to the tip. The connecting support rod portion 452 also may have a circular cone shape from the base portion 451 to the tip. The base portion 451 may be a combination of a rectangular cylinder and a pyramid.

As shown in the example of FIGS. 5(D)(a) and 5(D)(b), the connecting support rod portion 452 has a circular cylinder shape from the base portion 451 for a predetermined length, and has three poles which are thinner than the diameter of the circular cylindrical portion from the circular cylindrical portion to the tip. The connecting support rod portion 452 may be formed by poles from the base portion 451 to the tip, and the number of poles may be one or more. By this arrangement, it is possible to conduct an effective sterilization by coating the entire structure with a sterilization fluid during a sterilization process.

As shown in FIGS. 3(A), 3(B), and 3(C), the center support rods 46 are positioned in the center portion of the holder 4, and the number of the center support rods is two in this example, however it may be one, three or more. The center support rod 46 may have a shape which is same as the shape of the side support rod 45. As shown in the example of FIGS. 6(a) and 6(b), the center support rod 46 may have a shape of a rectangular cylinder having a crisscross cross-section shape from the basal plate portion 41 to the tip, or a rectangular cylinder, a circular cylinder or an elliptic cylinder having a cross-sectional shape extending radially in three directions (when the center support rod 46 has a shape shown in the example of FIGS. 6(a) and 6(b), it is not necessary to form the communicating hole 47).

It is preferable to mold integrally the basal plate portion 41, the tubular portion 42, the side support rod 45 and the center support rod 46. By the integral molding, it is possible to avoid residual bacteria issues in the joint gap between these members.

When the holders 4 are stacked, the tip of the connecting support rod portion 452 of the side support rod 45 of a holder 4 is inserted in the connecting hole 47 on the base end portion of the side support rod 45 of another holder 4 which is already installed (a similar operation is conducted when the center support rod 46 has a structure having a connecting hole 47). By repeating this operation, the stacked arrangement shown in FIG. 7 is obtained. By using such a structure, it is possible to reduce the contact area between the tip surface of the side support rod 45 or the center support rod 46 of the holder 4 and the container bottom portion 21 or the connecting hole 47, and thereby it becomes possible to conduct a sufficient sterilization of the contact portions. It is also possible to conduct an assured sterilization by such a structure of the holder 4 even when the holders 4 are stacked, and thereby it is possible to conduct a sterilization of a large number of medical devices at one time.

[Embodiment 2]
